if all whom. it muy concern:

Be it known that we, Tnnononn PoNsAn and 'tmncns. (I .1. Brill-:notturna citizens, of f' l'nited States` and residents, respectively, el" South Omaha and Omaha, in the. reunir of Douglas and State of ebrasla, have invented certain new and useful lm proteinen s in Ensilage-lutters, of which the foihnvinf a. specitication. Our invention relates to the class of machiites:{generali} known as ensilage cut-ters or silo till!A n: bjeet or" our invention to provide t oi this class especially adapted for the cut-ting of various forage crops, such as i alfalfa, clover or the like,`wliich hare been cured and baled and which it is desired to l cut into uniform sections preparatory to l further cutting,V grinding or crushing o "erations necessary in the production of alfalfa meal and the like.

Although especially ada ted for the above purpose our machine may ne advantageously employed for the cutting o materials in the used for ensilage.

Our invention has particular referenee to the feeding devices .v ich are arranged to rei eeive mats of varying thickness of the materials, as fed from me broken bales, to Carry the mats to the cutter blades, drive the same thercinto at. a speed proportional to the speed of the cutter blades, and retain a hold on the mats until the. extreme rearward portion thereof is engaged and cut by the lades into uniform lengths.

In the accompanying drawings Figure 1 is a longitudinal set-tion of a machine of the class described, showing the lportion thereof embodying: our invention. fig. L), is a side elevation thereof, and Fig. 1; is a plan View of the same.,

In the constructie'm shown we provide a suitable frame 1 u )on which, near one end thereof, is mounted a shaft 22 which carries a cutting reel consisting of spiders 4 carrying a. number ot helical cutter blades 3, as shown in Fig. 1. The cutting reel is inclosed by a casing 5 having a hinged lid 6 and a discharge spout 7.

Aty the rearward side of the cuttingr reel is a transversely extendingbar 8 which carries i the fixed cutter blade t) in s position to coreel. From the transverse bar S a table. 1t) extends rearwardly, curving shghtly downg' cams 17 and rollers 1S linger in Fig. 1.

- have no tendency to carry they same l ward and terminating adjacent the. front end ot' the horiaontal slat'eonreye'r 11.

Above the curved portion of the table 10 is a trans: rsely extending shaft 12 carrying a number ef disks 13 on which are loosely pivoted the feed'lingers 14. Each of said. feed fingers consists of a horn-shaped body carried by a shank extending approximately at right angles to the longitudinal axis of the hom-shaped body, said shank .having a curvetlheel surface of radius sliglttl) less than that of the disks 13. Behind the disks 13 is a transversely extending beam 15 from the iront side. of which brackets 16 extend forwardlyv between the disks and support the ad jacentI the. disks, as shown in Figs. 1 and 3. turned in the direction indicated by the arrow in Fig. 1, the curved heel surfaces of the feed fingers are engaged bythe cams 17 and turned outwardly as shown by the rearward The lingers are maintained in this outwardly-turned position, by engagementwith the said cams and the rollers 1S, Until the. )Joints thereof reach a. )osition in advance oi a vvertical line passing through the center oi" the shaft 12, whereupon, passing out of engagement with the rollers and meetingr with a. certain resistance from the materials engaged thereby, the lingers are drawn up almost vertically out of the material and up with thorn.

Behind and slightly below the transrerse beam 1:3 is a shaft. 19 to which are pirotally connected the pressure 'platesfltl which eX- tend forwardly therefrom, below the beam l5 and between the disks 13, terminating` adjacent the cuttingreel and above the fixed cutter blade. t). 1n the under side of the beam 15 are formedsuitable pockets or oups in which are held coil springs 21 which b'ear upon the plates 2t) and yit'ldably press the. sumo downward. B v upward pressure from materials passing through the feed throat formed between the plates 20 and the table' 1U, said plates may be raised to a position as shown by dotted lines in Fig. 1. As any of the plates may be depressed while an adfoming plate is in raised position, the side. shields provided at the adjoining edges of the being of a height, total movement of from beneath one of anothta is pre- L 2'2 are. pistes. Said shields 22 slightly greater than the the plates, any opening pia-te and over the top ritratta orinon. f

As the disks 13 are Y connected with the slotted arm 3;. At the gaged by' the feed fingers t4 and pushed 9o lower end of the slotted :.rni 32 is a eireuthereby through the throat to the engaging larv portion inclosin,r an eccentric 33 which' edges of the fixed und rotary cutter blades. is connected by the. stud 54: with the frame Masses or mats of the materials, as dis- 1. The eccentric 33 provided with a engaged from bales or as com ressed behandle 35 which may be turned to theposi 'tween the corrugated roller and) conveyor, 95

vented and the materiels confined within the feed throat.

The machine may be conveniently driven by :i beltapplied to the iyLwheel pulley1 .53

rounding the shaft and worin, and there beingr bearing.` 25`formed in ieupper part thereof for the worm-wlieel-s.stt 26. T he reanwurdly extending portion of the shaft 2 pi sses through a bearing and has formed at the end thereof a worin 2S adapted io engage. a worin-wheel 29 placed on the end of the shaft 12. Collars 30 are placed on the shaft 2G :it cach'side of the bearings 25 and 27, for holding said parts, in proper relstive position. On the under side of1he bearinU 27 is a transversely extending portion tirough which passes a sleeve end bolt 3l by which the bet-:ring is adjustiibljf tion shown by dotted lines in Fig. 1l, thus drawing,r downwardly the slotted arm, the bearing 27 and shaft 26, tiitingrthe casing 24 about the axis of the shaft 2 and diseiigaging the worin 2S from the worm-wheel 29, as also indicated byhdotted lines in Fig. 2. By thus engaging or discngaging the driving connection between the cutter shaft 2 and the feed shaft l2 the feeding of materials muy be started or stopped at the n ill of the operator` Pins 3G are provided on the. frame l on which the handle 35 may rest at its extremes of movement. By adjusting the position of the bearing 27 relative to ihefslotted arm 32. different sized worm-wheels may be placed on the shaft 12 and the speed ratios between the shafts l and 12 thus varied.

To facilitate the feeding` of loose liiiiterials by compressing the suine into compact masses which may bc readily engaged and 'driven through the feed throatby the fingers 14, the),'ichlingly-impressmi corrugated roller 37 is provided, the. saine being disposed transversely above, the sia conveyor and inimediatelvxY behind thcshaft ttl. The shaft .3X of said corrugated roier is iournzzled in the ends of the radius liars 3ft which arefY pivotally connected with xiie frame l above the conveyor shaft `lt). Near. tho rt-.zu'n'ard ends of the' radins bars :irc winner-ted the rods 4l which extend downnardl)1 therefrom i through the lirnckets 42 on the frame. coil t lower ends of the rods, the. radius bars and corrugated roller being thus yieldin'gly pulled do\\'n\\'.-irdly by the tension of said springs. 43. rflic shit conveyer and corruated roller 5 carried on the shaft 2. {ln one end of the may be convenientlyv driven by the means l shaft '.2 is a worm, the same engaginga woriushown in Figs. 2 and 3, in which is repre- Wheel, ,both worm and worin-wheel bei g sented a sprocket 45 laced on the shaft. 12, indicated by dotted lines in Fig. 2 and being a chain 4C extending t ierefroni and driving a inelosed' in :in ordinati worm-:intl-worm' sprocket 47 working loosely on the stub shaft 1g Wheel-casing 2- having n lower portion suremployed for pivoting one of the, radius bars *F 3Q.

Materials placed r upon the slat convejyer l1 are carried forward thereby to the trible 10 and, entering the throat formed between the said table and tlieyicldably impressed plates 2t), are en are securely held by the ends of the iressure plat es until the last portions of siii mzitsor,
